    The shaft diameter is 3/4 inch and it is about 6 inches long. On the end of the shaft there is an end plate that serves as a thrust bearing and it has a spiral groove that appears to pump lubricant through the bearings. There is a cup inside the housing that appears to sling the lubricant back to the end plate.

    I would like to know what years this fan assembly was used?

    Was it lubricated with oil or grease and what kind?

    What kind of a seal was used where the shaft exits the housing?


    I don’t no what years theses were used,but my owners manual says to use engene oil. George


    They were used 29 to 38. They can be converted to modern seals so they won’t leak. I replaced my 36 with modern timkin bearings and seals, no leaks for 20 years…. Ed
